The PCI-Express bus off the U4/CPC945 bridge supports direct DMA to all of memory, bypassing the DART iommu, for 64-bit capable devices. This adds support for it on Bimini and Apple Quad G5's in order to improve DMA performances of cards using that slot (the x16 graphics slot). Tested with an Intel ixgbe 10GE card.

Since the cpu accounting code uses the hypervisor dispatch trace log now when CONFIG_VIRT_CPU_ACCOUNTING = y, the previous commit disabled access to it via files in the /sys/kernel/debug/powerpc/dtl/ directory in that case. This restores those files. To do this, we now have a hook that the cpu accounting code will call as it processes each entry from the hypervisor dispatch trace log. The code in dtl.c now uses that to fill up its ring buffer, rather than having the hypervisor fill the ring buffer directly. This also fixes dtl_file_read() to handle overflow conditions a bit better and adds a spinlock to ensure that race conditions (multiple processes opening or reading the file concurrently) are handled correctly.

Currently, when CONFIG_VIRT_CPU_ACCOUNTING is enabled, we use the PURR register for measuring the user and system time used by processes, as well as other related times such as hardirq and softirq times. This turns out to be quite confusing for users because it means that a program will often be measured as taking less time when run on a multi-threaded processor (SMT2 or SMT4 mode) than it does when run on a single-threaded processor (ST mode), even though the program takes longer to finish. The discrepancy is accounted for as stolen time, which is also confusing, particularly when there are no other partitions running. This changes the accounting to use the timebase instead, meaning that the reported user and system times are the actual number of real-time seconds that the program was executing on the processor thread, regardless of which SMT mode the processor is in. Thus a program will generally show greater user and system times when run on a multi-threaded processor than on a single-threaded processor. On pSeries systems on POWER5 or later processors, we measure the stolen time (time when this partition wasn't running) using the hypervisor dispatch trace log. We check for new entries in the log on every entry from user mode and on every transition from kernel process context to soft or hard IRQ context (i.e. when account_system_vtime() gets called). So that we can correctly distinguish time stolen from user time and time stolen from system time, without having to check the log on every exit to user mode, we store separate timestamps for exit to user mode and entry from user mode. On systems that have a SPURR (POWER6 and POWER7), we read the SPURR in account_system_vtime() (as before), and then apportion the SPURR ticks since the last time we read it between scaled user time and scaled system time according to the relative proportions of user time and system time over the same interval. This avoids having to read the SPURR on every kernel entry and exit. On systems that have PURR but not SPURR (i.e., POWER5), we do the same using the PURR rather than the SPURR. This disables the DTL user interface in /sys/debug/kernel/powerpc/dtl for now since it conflicts with the use of the dispatch trace log by the time accounting code.

This arranges for the lppaca structs for most cpus to be dynamically allocated in the same manner as the paca structs. If we don't include support for legacy iSeries, only the first lppaca is statically allocated; the rest are dynamically allocated. If we include legacy iSeries support, then we statically allocate the first 64 lppaca structs, since the iSeries hypervisor requires that the lppaca structs be present in the data section of the kernel image, but legacy iSeries supports at most 64 cpus. With CONFIG_NR_CPUS, the kernel image size for a typical pSeries config went from: text data bss dec hex filename 9524478 4734564 8469944 22728986 15ad11a ../test-1024/vmlinux to: text data bss dec hex filename 9524482 3751508 8469944 21745934 14bd10e ../test-1024/vmlinux a reduction of 983052 bytes overall.

Currently we have the lppaca structs as a simple array of NR_CPUS entries, taking up space in the data section of the kernel image. In future we would like to allocate them dynamically, so this abstracts out the accesses to the array, making it easier to change how we locate the lppaca for a given cpu in future. Specifically, lppaca[cpu] changes to lppaca_of(cpu). Signed-off-by: Paul Mackerras <paulus@samba.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

The POWER architecture does not require stcx to check that it is operating on the same address as the larx. This means it is possible for an an exception handler to execute a larx, get a reservation, decide not to do the stcx and then return back with an active reservation. If the interrupted code was in the middle of a larx/stcx sequence the stcx could incorrectly succeed. All recent POWER CPUs check the address before letting the stcx succeed so we can create a CPU feature and nop it out. As Ben suggested, we can only do this in our syscall path because there is a remote possibility some kernel code gets interrupted by an exception that ends up operating on the same cacheline. Thanks to Paul Mackerras and Derek Williams for the idea. To test this I used a very simple null syscall (actually getppid) testcase at http://ozlabs.org/~anton/junkcode/null_syscall.c I tested against 2.6.35-git10 with the following changes against the pseries_defconfig: CONFIG_VIRT_CPU_ACCOUNTING=n CONFIG_AUDIT=n CONFIG_PPC_4K_PAGES=n CONFIG_PPC_64K_PAGES=y CONFIG_FORCE_MAX_ZONEORDER=9 CONFIG_PPC_SUBPAGE_PROT=n CONFIG_FUNCTION_TRACER=n CONFIG_FUNCTION_GRAPH_TRACER=n CONFIG_IRQSOFF_TRACER=n CONFIG_STACK_TRACER=n to remove the overhead of virtual CPU accounting, syscall auditing and the ftrace mcount tracers. 64kB pages were enabled to minimise TLB misses. POWER6: +8.2% POWER7: +7.0% Another suggestion was to use a larx to something in the L1 instead of a stcx. This was almost as fast as removing the larx on POWER6, but only 3.5% faster on POWER7. We can use this to speed up the reservation clear in our exception exit code. Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

This adds the equivalent of csum_and_copy_from_user for the receive side so we can copy and checksum in one pass. It is modelled on the generic checksum routine. Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

We use the same core loop as the new csum_partial, adding in the stores and exception handling code. To keep things simple we do all the exception fixup in csum_and_copy_from_user. This wrapper function is modelled on the generic checksum code and is careful to always calculate a complete checksum even if we only copied part of the data to userspace. To test this I forced checksumming on over loopback and ran socklib (a simple TCP benchmark). On a POWER6 575 throughput improved by 19% with this patch. If I forced both the sender and receiver onto the same cpu (with the hope of shifting the benchmark from being cache bandwidth limited to cpu limited), adding this patch improved performance by 55% Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

The main loop of csum_partial runs very slowly on recent POWER CPUs. After some analysis on both POWER6 and POWER7 I came up with routine below. First we get the source aligned to a double word, ignoring any odd alignment to keep things simple. Then we do 64 bytes at a time, with an entry and exit limb of a further 64 bytes. On both POWER6 and POWER7 this should be as fast as we can go since we are limited by the latency of the adde instructions. To test this I forced checksumming on over loopback and ran socklib (a simple TCP benchmark). On a POWER6 575 throughput improved by 11% with this patch.

The dlpar code can cause a deadlock to occur when making the RTAS configure-connector call. This occurs because we make kmalloc calls, which can block, while parsing the rtas_data_buf and holding the rtas_data_buf_lock. This an cause issues if someone else attempts to grab the rtas_data_bug_lock. This patch alleviates this issue by copying the contents of the rtas_data_buf to a local buffer before parsing. This allows us to only hold the rtas_data_buf_lock around the RTAS configure-connector calls.

In f761622e we changed early_setup_secondary so it's called using the proper kernel stack rather than the emergency one. Unfortunately, this stack pointer can't be used when translation is off on PHYP as this stack pointer might be outside the RMO. This results in the following on all non zero cpus: cpu 0x1: Vector: 300 (Data Access) at [c00000001639fd10] pc: 000000000001c50c lr: 000000000000821c sp: c00000001639ff90 msr: 8000000000001000 dar: c00000001639ffa0 dsisr: 42000000 current = 0xc000000016393540 paca = 0xc000000006e00200 pid = 0, comm = swapper The original patch was only tested on bare metal system, so it never caught this problem. This changes __secondary_start so that we calculate the new stack pointer but only start using it after we've called early_setup_secondary. With this patch, the above problem goes away.

Commit 0fe1ac48 ("powerpc/perf_event: Fix oops due to perf_event_do_pending call") moved the call to perf_event_do_pending in timer_interrupt() down so that it was after the irq_enter() call. Unfortunately this moved it after the code that checks whether it is time for the next decrementer clock event. The result is that the call to perf_event_do_pending() won't happen until the next decrementer clock event is due. This was pointed out by Milton Miller. This fixes it by moving the check for whether it's time for the next decrementer clock event down to the point where we're about to call the event handler, after we've called perf_event_do_pending. This has the side effect that on old pre-Core99 Powermacs where we use the ppc_n_lost_interrupts mechanism to replay interrupts, a replayed interrupt will incur a little more latency since it will now do the code from the irq_enter down to the irq_exit, that it used to skip. However, these machines are now old and rare enough that this doesn't matter. To make it clear that ppc_n_lost_interrupts is only used on Powermacs, and to speed up the code slightly on non-Powermac ppc32 machines, the code that tests ppc_n_lost_interrupts is now conditional on CONFIG_PMAC as well as CONFIG_PPC32.

VIA VT6306, VIA VT6308, and NEC OrangeLink controllers do not write packet event codes for received PHY packets (or perhaps write evt_no_status, hard to tell). Work around it by overwriting the packet's ACK by ack_complete, so that upper layers that listen to PHY packet reception get to see these packets. (Also tested: TI TSB82AA2, TI TSB43AB22/A, TI XIO2213A, Agere FW643, JMicron JMB381 --- these do not exhibit this bug.) Clemens proposed a quirks flag for that, IOW whitelist known misbehaving controllers for this workaround. Though to me it seems harmless enough to enable for all controllers. The log_ar_at_event() debug log will continue to show the original status from the DMA unit.
